The present study has been done to find a suitable way to produce Wood-Plastic Composites (WPC) from Polyethylene terephthalate (PET) in accordance with the specifications mentioned in the National Standard of Iran. The experimental samples were prepared with 45 x 45 cm area; in 5, 10, and 16 mm thickness; 0.8 gr/cm2 density; altering weight proportions between % 20 to 49 of residual PET based on the total weight of the samples; using hot press method and these factored were as follows: Modulus of rupture (MOR); Internal Bond (IB) in vertical direction to the surface of samples; Swelling; Water adsorption after 2 and 24 hours submersion in water. The outcome of the present study proves that there is a good possibility to produce Wood-Plastic Composites with different thicknesses from PET residuals in 200 degrees centigrade under 3 min hot press; we achieved producing layered boards of 5 mm thickness, having %20 residual PET, %10 Poly-ethylene, and %70 saw-dust, in compliance with the above mentioned standard
